cut springs? are you mad ? springs are made with certain number of coils and wire diameter for verry specific reasons. Bump length ,droop length, ride length ,weight on spring at ride height are all dimentions you must know before you even start looking for a spring. I dont want to over complicate your project but you will be much happier with the result if you do some more homework first. Check out the eibach web site, their catalogue has some good tech info that can help you find all the right info for your aplication, sorry for the long winded answer but its not as easy as just cutting a spring.
